3rd, fixing device 4 is held in the lengthwise both ends of clasp electronic card 200 respectively.
The insulating body 1 is provided with connects both sides along the two side 11 of longitudinally extension, along the horizontal direction of insulating body 1
The end walls 12 of the end of wall 11, so as to which the insulating body 1 forms the central slot 101 extended along longitudinally, for housing
Electronic card 200；The insulating body 1 also has is connected and houses several ends of above-mentioned conducting terminal 2 with the central slot 101
Sub- accepting groove 102, it is in electrical contact with electronic card that each conducting terminal 2 protrudes into central slot, and provided with extending insulating body
Outer weld part 21, for being electrically connected with above-mentioned printed circuit board (PCB).The end wall 12 is higher than side wall 11 into tower-like, rotation
Latch 3 includes main part 30, and the lower end of main part 30 houses what end wall 12, and upper end is provided with operating portion 31 and position positioned at outside
In the pintle hook lock portion 32 of the opposite side of operating portion 31, it is pivotally connected so as to rotate latch 3 in wall 12 at one end, and exist relative to insulating body
Open or close and swing between state, pintle hook lock portion 32 latches or left the respective slot of electronic card 200 with swing.
The fixing device 4 formed be assembled on insulating body end wall 12 main part 40, main body extension and with
Buckle arm 41, the main body of insulating body interference cooperation are integrally protruded out with the bullet of clasp electronic card towards central slot 101
Property support arm 42 and positioned at the limiting section 43 for flexibly supporting the outside of arm 42；The end wall 12, which has, houses buckle arm 41, elasticity
The resettlement groove 121 of arm 42, limiting section 43 is supported, the buckle arm 41 can be described in snap fit positioning what in resettlement groove, by fixing device 4
Strong fix is on insulating body end wall 12；The end for flexibly supporting arm 42 has step-like pressure section 421, with smaller
Area compress in the groove 201 of electronic card, can relative increase clasp dynamics；Arm 42 is flexibly supported along perpendicular to longitudinally
Abutting direction extend downwardly so that resistance gradually increases during electronic card grafting, extracts when starting that then resistance is maximum, pintle hook lock effect
It is good；The main part 40 of the fixing device 4 has central axis along above-mentioned abutting direction, and flexibly supporting the bearing of trend of arm 42 can be with
The central axis forms the angle less than 45 degree, while obtaining preferably elastic, reduces the length of connector as far as possible.Along vertically
